The 2HJB-1200L substrate mixer is primarily designed for the intensive, high-efficiency production of seedlings for vegetables, medicinal herbs, flowers, and tobacco. Capable of uniformly mixing various substrates and additives to meet diverse production requirements, it can operate as a standalone unit or be integrated with a seeding line to form a complete seedling production system.

The mixer has specific installation requirements: it operates on an AC 380V/50Hz power supply and requires an installation area measuring 5–8 meters in length and 3–5 meters in width. The equipment must be placed on a paved, hardened surface or on fixed concrete pads of appropriate specifications to facilitate coordinated operation with other seedling production equipment; the suitable indoor operating temperature range is 0–40°C.

The substrate mixer features a comprehensive operational workflow, sequentially handling substrate loading, water addition and mixing, and fertilizer incorporation, followed by automatic discharge via a tilting mechanism. With a single-batch mixing capacity of up to 1,000 liters, the equipment includes automatic lifting and discharge functions; it ensures thorough mixing without compromising the substrate’s chemical composition or physical structure. Water input is adjustable to meet specific moisture requirements, and the mixing cycle ranges from 3 to 10 minutes. The unit is equipped with an aluminum watering system featuring multiple nozzles that provide full coverage of the mixing chamber’s cross-section, with adjustable flow rates. The discharge system offers an adjustable tilt angle of up to 42 degrees in both directions, utilizing two adjustable limit switches to accommodate various discharge scenarios.

Substrate Mixer Specifications: Model 2HJB-1200L; dimensions (L×W×H) of 3690×1640×2140 mm; total weight of 994 kg; total power of 2.6 kW. It is equipped with two motors: a 1.5 kW motor for lifting, mixing, and conveying, and a 1.1 kW motor for adjusting the discharge angle. The mixing capacity is ≤1000 L, with a mixing time of 2–10 minutes.

The machine body is constructed from high-strength carbon steel with an electrostatic powder coating finish, while the lifting chain plates are made of stainless steel. The water spray pipe is aluminum, and the conveyor belt features a dark green matte PU material (Yongli brand). It utilizes a chain-lifting, motor-driven transmission system and is controlled via mechanical rotary knobs.

This substrate mixer replaces traditional manual mixing methods, effectively reducing labor costs in the seedling preparation process. It ensures consistent substrate moisture and material uniformity, thereby guaranteeing high-quality seedling emergence. It serves as a practical piece of auxiliary equipment for large-scale seedling production in seedling factories and major cultivation bases.
